摘要： In a reference (n-th) machining pass, the wire travels along a machining route RTn and passes through a reentrant angular corner with wire position WMn, producing a workpiece edge Hn. In the following (n+1)-th machining pass, the wire travels along a machining route RTn+1, but the straight sections preceding and following the corner are replaced with a circular arc route so that the wire passes smoothly through a straight route, then a circular arc route, and then a straight route. The radius of curvature of the circular arc route is determined in the controller on the basis of the difference between the offset specified for the reference (n-th) machining pass and the offset specified for the (n+1)-th pass in which the circular arc route is inserted. Accordingly, the machining margin does not increase in the reentrant angular corner and the machining accuracy is thereby improved.
摘要翻译：在参考（第n）个加工道次中，线沿着加工路径RTn行进，并通过具有线位置WMn的可重入角角，产生工件边缘Hn。在下面的第（n + 1）次加工中，线沿着加工路径RTn + 1行进，但是角部前后的直线部分被圆弧路线替代，使得线材顺利地通过直线路线，然后是圆弧路线，然后是直线路线。圆弧路径的曲率半径基于对第（n）个加工通过指定的偏移与第（n + 1）次通过指定的偏移量之间的差异，在控制器中确定，其中插入圆弧路线。因此，在凹入角角中的加工余量不增加，从而提高了加工精度。

摘要： Set feed speed is lowered when a short circuit is detected in a range within which machining is unstable, the range starting from the point at which discharge is detected after machining starts from a machining start point, thus control is carried our according to a machining rate, thereby preventing successive occurrence of short circuits. When machining proceeds beyond the unstable range, the lowered feed speed is returned to the normal feed speed.

摘要： A controller for a wire cut electric discharge machine which can provide stable finish machining and corner-region machining with high corner-form accuracy. An electric discharge gap detection device detects a voltage between a wire electrode and a workpiece. A machining rate detection device obtains an average machining voltage and a drop voltage value Ex which is a difference between the obtained average machining voltage and a no-load voltage. A comparison device obtains the ratio Es/Ex between a reference drop voltage value Es stored in a reference machining rate relative value storage device and the obtained drop voltage value Ex. In machining of a corner portion, when the drop voltage value Ex exceeds a entrance-into-corner determination reference machining rate, a set feed speed switch device supplies a corner set feed speed, and when the machining of the corner portion finishes, so that the drop voltage value Ex decreases to a leaving-from-corner determination reference machining rate or lower, the set feed speed switch device supplies a normal set feed speed. A feed pulse calculation device obtains a feed speed which makes the rate of machining constant, on the basis of the ratio Es/Ex and the supplied feed speed, to thereby drive motors. Since the rate of machining is kept constant, the surface accuracy of finish machining is high and stable machining can be performed.

摘要： A controller for a wire electric discharge machine which can achieve stable machining with high surface accuracy without requiring adjustment of a gain or the like in wire-electrode feed control. A discharge gap detection unit detects a voltage between a wire electrode and a workpiece. An amount-of-machining-per-unit-distance change detection unit obtains an average machining voltage, and a voltage drop EX that is a difference between the obtained average machining voltage and a no-load voltage. A comparative determination unit obtains a ratio ES/EX between a reference voltage drop ES stored in a reference-amount-of-machining-per-unit-distance relative value storage unit and the drop voltage EX. A feed pulse arithmetic unit obtains a feed speed that makes the amount of machining per unit time constant, on the basis of the ratio ES/EX and a predetermined feed speed, and distributes feed pulses to motors to thereby move the wire electrode relatively to the workpiece. Since the amount of machining per unit time is kept constant, the surface accuracy in finishing is high and stable machining can be performed.

摘要： A discharge pulse number generated between a wire electrode and a workpiece is counted every predetermined time. A ratio Px/Ps of this counted value Px to the reference pulse number Ps will be determined to control an amount of coolant in response to this ratio Px/Ps. Also, in response to this ratio Px/Ps, an amount of movement within predetermined time is controlled. Further, through the ratio Px/Ps and the like, quiescent time to be controlled by the detection voltage generator is controlled. Thereby, surplus supply of energy is prevented, the machining speed and machining precision is improved and any disconnection of the wire electrode is avoided.

摘要： A controller of a wire electric discharge machine monitoring a change in thickness of a workpiece and a current density in real time, promoting a machining speed by preventing occurrence of disconnection of a wire electrode even when the change in the thickness is caused in the workpiece and improving a dispersion in a machining enlargement amount. A machining distance calculating device outputs a signal at each progress of machining by a predetermined distance &Dgr;x. A main pulse number storing device counts a main pulse number for discharge machining outputted from a main pulse generator during a time period of the signal. A thickness calculating device calculates the thickness from a reference main pulse number in machining a reference thickness, the main pulse number stored to the main pulse number storing device and the reference thickness at each reception of the signal. The calculated thickness, further, a machining current, the machining speed and a machining current density are displayed. A discharge pause time control device changes a pause time period of voltage applied to the wire electrode and the workpiece in accordance with a thickness change rate and adjusts the machining current density such that no change is caused before and after the change in the thickness.

摘要： Machining state information is acquired for each predetermined period by performing test machining by an electric discharge machine, and the acquired machining state information is compared with reference machining state information, whereby whether a machining state is satisfactory or not is determined. If the machining state is determined to be unsatisfactory, set items of a machining condition are adjusted. Thereafter, test machining is actually performed again, and the machining condition is adjusted by changing the set items if the machining state is determined again to be unsatisfactory. Thus, the acquisition of the machining state information, determination of the machining state, and adjustment of the machining condition are repeated so that satisfactory machining is finally determined.
